Powdery spots on leaves

GrowStedyFlostarted grow question 3 years ago

Noticed powdery spots on some leaves this week (week 23-24). Plant is over 10 ft tall. Only fed water and got plenty of sun. What should I do to ensure a healthy harvest?

Thanks for the all the info!! All great suggestions but due to lack of available funding (KindaBrokeRightNow😁) I'll have to go with items I currently have available. Thus I'm pouring some milk into my sprayer mixed with water (4/6). Thanks @HerbalEdu

Oof - you gotta get on that quick. I use Green Cleaner it’s my favorite but it’s expensive. Dr zymes is decent for mildew too but didn’t work as well for me when bugs needed exterminated.

That's powdery mildew. You need to lower the humidity and increase airflow, but since there's no real way to do that on an outdoor grow you should look into a fungicide to spray on the leaves. There's a bunch of different brands on the market. Do a little research to decide which one is best for you.

White powdery mildew in late flower What's your best remedy to remove it on flowering plants? I just found it after I had forgotten to replace on of the fans when I left them for a few days. What can I do to remove it as quickly as possible without ruining the buds? I'd prefer not spraying them with milk.

Possible mold/mildew - I ask a ton of grow questions but figure someone else might learn if I do well or f up. Good community here Mildew? This has been on certain leaves of my plants since I got them so I didn't think much of them. But as I'm about two weeks into flowering, I want to see if this is possibly an issue. Have okay airflow in the tent but could be better. Humidity is 55% atmosphere. Thoughts?
